Hi Paul, thanks for the reply. The pre board I am using already has a relay resistor volume control which sits on the output side rather than the more conventional pot then gain stage so I was hoping just to add input switching with ht bypass without the volume control for this project. Is that possible with this setup?
Cheers,
Gordon

I tried with 60 steps, and the hump moved to step 29-30. This looks like a problem with the middle step.
I build another PCB, this time with NSL-32SR3 instead of SR2. Not only that it worked, there is also no volume bump in the middle.
You could just use it for input switching. Optionally you could strip out all the code that drives the LDRs etc.
Good stuff , any idea how to use say 3 inputs one of which is the ht bypass which connects input to output , totally bypassing the gain stage?😕
Hi Paul
Yes it working good now with 4 inputs and 2 outputs.But i have little noise at the middle 30-35 of volume i think something happen with the way i pull out the Gnd input -output ,i think must pull out the cables from the same spot of GND.
You could do this but you would need to cut a number of tracks on the input board for the third input so that you could use it instead as a c/o relay at the output.
Absolutely, I have already built four. I am fitting it in all of my amps.

When I compared speed of my ssd1306 oled code with lcd one, I realised that oled is much too slow. I am now working on speeding up u8glib variant or reducing mem usage of adafruit lib. Any suggestions welcome.

I managed to write a very fast and compact OLED VxD code using SSD1306 Ascii library. It seems to have even faster refresh rate than LCD.
